E1962B Datasheet, PDF (2/26 Pages) Agilent(Hewlett-Packard) – cdma2000/IS-95/AMPS Mobile Test Application

E1962B Functionality Overview
With advanced features and superior performance, the E1962B is
designed for high-volume manufacturing and wireless device
development, allowing you to finalize product designs and
minimize time to volume.
CDMA forward link emulation
The fully-coded IS-2000 forward-link emulation supports radio
configurations 1 through 5 and all supplemental channel data
rates associated with those configurations. Comprehensive signal
generation capabilities including all applicable CDMA channels,
modulation, and an AWGN source (1.8 MHz minimum bandwidth).
Flexible user control of the forward link emulation is provided
through easy-to-use front panel control and remote GPIB. Option
E1962B-401 adds cdma2000 Release A protocol support and
includes the new F-BCCH and F-CCCH channels.
CDMA authentication
Option E1962B-403 adds authentication capabilities when
operating in the active cell modes using the IS-95 or IS-2000
systems. Authentication supports two new one-button
commands: unique challenge and SSD update. The global
challenge function can be turned on or off to support
authentication with most call processing functions. User
authentication parameters include A-key (decimal), RAND (hex),
RANDU (hex), and RANDSSD (hex). The reported global challenge
results include the AUTHU expected value, the AUTHU received
value and a pass/fail result and the RANDC expected value, the
RANDC received value, and a pass/fail result. Other results
include the count and AUTH_MODE. The reported unique
challenge results include the AUTHU expected value, the AUTHU
received value and a pass/fail result. Pass/fail results are also
available for SSD updates.

Fading tests
E5515C Option 004 adds a rear panel digital bus that enables
fading when it is used with Agilent’s Baseband Studio for fading
solution. In conjunction with the N5101A Baseband Studio PCI
card and the Agilent N5115A Baseband Studio for fading software,
the E1962B provides receiver fading tests with unprecedented
accuracy and repeatability, at a very attractive price point.
Baseband I/Q data from the Agilent E5515C wireless
communications test set is sent via the digital bus to the N5101A
fading card in an external PC. The N5115A fading software
configures the PCI card to perform the user-selected fading
profile. After digital fading, AWGN can be digitally added to the
waveform. The resulting waveform is then returned to the test set
via the digital bus for modulation. This solution eliminates almost
all associated calibrations and provides rock-solid repeatability.
Multi-unit synchronization
Option 406 allows any test set to be time-synchronized to another
test set that is running either a CDMA or 1xEV-DO test application
or lab application. The multi-unit synchronization supports
simulation of mobile behaviors with two base stations. Typical
applications are idle/softer handoff, pilot detection, and hybrid
mode simulation.
